AI Technical Summary

Benefits of technology

The tape-type fluorine preparation maintains a stable fluorine concentration for an extended period, providing high anti-cariogenicity and is environmentally friendly, as it is self-degraded after use, reducing discomfort and improving adherence compared to traditional methods.

Problems solved by technology

However, since it is noted that the fluorine gel is hydrophilic, has a short contact time with teeth, presents a risk when swallowed during application, and discolors and erodes previous esthetic restoration, recently, the use of fluorine varnish has been increasing.
However, the fluorine varnish has a resin as a main component, and thus causes inconveniences such as temporary discoloration of teeth, an unpleasant flavor, and sticky texture in application.
In addition, the fluorine varnish does not stay attached to the teeth surface for a long time and is easily removed due to saliva or food, and thus a suitable fluorine concentration cannot be maintained in an oral cavity for a long time.

examples

[0045]A polymer solution was prepared by adding 15 g of a hydrophilic polymer to 85 g of distilled water and stirring the resulting solution at 80° C. for 2 hours. In addition, 3 g of polyethylene glycol was added to the polymer solution, and the resulting solution was stirred at 80° C. for 2 hours. In addition, 2.5 g of sodium fluoride and 7 g of a carboxyvinyl polymer were added, stirred, and then bathed at 80° C. for 115 minutes, thereby forming a sol. Moreover, the sol was plasticized into a tape-type pressure-sensitive adhesive sheet using a planar film manufacturer, and dried at 60° C. for 24 hours, thereby preparing a fluorine preparation.

[0046]In this Example, as the hydrophilic polymer, various kinds of fluorine preparations were prepared using polyvinyl alcohol (PVA) or sodium CMC alone, and a mixture of a PVA and sodium CMC. When the PVA and CMC were mixed, a content of the sodium CMC was changed.

Abstract

Provided are a tape-type fluorine preparation using a biodegradable polymer and a method of preparing the same, and preferably, a tape-type fluorine preparation which is attached to teeth to gradually release fluorine, thereby maintaining a suitable fluorine concentration in an oral cavity, and self-degraded after a certain amount of time, and a method of preparing the same. The tape-type fluorine preparation includes a pressure-sensitive adhesive sheet containing fluorine and capable of being attached to teeth, and the pressure-sensitive adhesive sheet is formed of a biodegradable hydrophilic polymer in an oral cavity to reduce a rate at which the fluorine is released.

Description

TECHNICAL FIELD[0001]The present invention relates to a tape-type fluorine preparation using a biodegradable polymer and a method of preparing the same, and more particularly, to a tape-type fluorine preparation, which is attached to teeth and gradually releases fluorine to maintain a suitable fluorine concentration in an oral cavity, and then is self-degraded after a certain amount of time, and a method of preparing the same.BACKGROUND ART[0002]It is well known that fluorine ions are applied to tooth tissue to provide reinforcement, and dental materials in which fluorine ion-releasing materials are blended are already being used to prevent and inhibit caries.[0003]As a representative method to prevent dental caries, a method of caring a dental plaque, a method of utilizing fluorine, a sealant method, or a dietary control method. Among them, starting from the research disclosed in 1938 by Dean, relating to a concentration of fluorine ions in drinks is inversely proportional to the o...
